Genotype-phenotype mapping

Definition

Genotype-phenotype mapping refers to the process of linking specific genetic variations (genotypes) to observable traits and characteristics (phenotypes) in an organism. This mapping helps in understanding how changes at the genetic level can influence physiological, biochemical, and morphological attributes, allowing researchers to investigate the underlying mechanisms of complex traits, especially in the context of metabolomics and genomics integration.
